Definitions
- At least some example embodiments relate generally to an electronic vaping (e-vaping or e-vapor) device.
- Electronic vaping devices are used to vaporize a pre-vapor formulation into a vapor. These electronic vaping devices may be referred to as e-vaping devices. E-vaping devices include a heater, which vaporizes the pre-vapor formulation to produce the vapor. The e-vaping device may include several e-vaping elements including a power source, a cartridge or e-vaping tank including the heater and a reservoir capable of holding the pre-vapor formulation.
- a power supply section for an e-vapor device includes a power supply section housing including a power supply portion and a heater assembly portion.
- the power supply portion includes a power supply
- the heater assembly portion includes a heating element and a support.
- the power supply is configured to selectively supply power to the heating element.
- the heating element includes a planar portion and first and second lead portions.
- the planar portion includes at least one filament.
- the first and second lead portions extend away from the planar portion.
- the support may support the heating element in the power supply section housing.
- the support includes a first slot and a second slot, and the first lead portion extends through the first slot, and the second lead portion extends through the second slot.
- the power supply portion and the heater assembly portion are releasably connected.
- the power supply portion and the heater assembly portion are releasably connected via a threading engagement.
- the filament defines an air channel through a central area of the planar portion.
- the filament includes stainless steel.
- the first and second lead portions extend away from the planar portion in a direction that is substantially perpendicular to the planar portion.
- a tip of the first lea portion and a tip of the second lead portion are bent in a direction that is parallel to the planar portion.
- the filament follows a circuitous path and defines an air channel through a central area of the planar portion.
- a width of the filament varies along the circuitous path.
- the width of the filament gradually increases in a direction away from the air channel.
- the filament includes a plurality of filament portions that are substantially u-shaped, and the plurality filament portions are connected to one another at end sections of each u-shape.
- a space between adjacent ones of the plurality of filament portions gradually increases in a direction away from the air channel.
- a heater assembly section includes a heater assembly housing and a heating element.
- the heating element includes a planar portion including at least one filament.
- the heating element includes first and second lead portions extending away from the planar portion.
- the support includes a support supporting the heating element in the heater assembly housing, the support including a first slot and a second slot, the first lead portion extending through the first slot, the second lead portion extending through the second slot.
- the planar portion is at a first end of the heater assembly housing, and the first and second lead portions extend through the first and second slots toward a second end of the heater assembly housing.
- the support is fixed in the heater assembly housing by at least one of a threading engagement, adhesive force and friction force.
- the first end has a first connecting portion
- the second end has a second connecting portion
- the first connecting portion includes keys for a detent connection.
- the first connecting portion includes a first threaded portion

- the first lead portion extends through first slot, and the second lead portion extending through the second slot.
- the first lead portion and the second lead portion are bent in a direction that is substantially parallel to the planar portion.
- the support includes a hollow conductive rivet extending through the through hole such that the conductive rivet is electrically connected to the second lead portion and electrically isolated from the first lead portion.
- a cartridge includes a cartridge housing having a closed end and an open end.
- the cartridge includes a channel structure defining an airway through the closed end and through the cartridge housing from the closed end to the open end, the channel structure defining a reservoir between the cartridge housing and the channel structure.
- the cartridge includes a porous substrate disposed in the cartridge housing at the open end.
- the cartridge includes a gasket disposed proximate to the open end to seal the reservoir, the gasket including at least one aperture to provide a fluid communication between the reservoir and the porous substrate.
- the channel structure is substantially cylindrical and passes through a central area of the cartridge housing.

- first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or section from another region, layer, or section. Thus, a first element, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiments.
- spatially relative terms e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like
- the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below.
- the device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
- Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of example embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, an implanted region illustrated as a rectangle will, typically, have rounded or curved features and/or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region.
- a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation takes place.
- the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of example embodiments.
